Starting Monday, Aug. 3, multiple Washington State highways on the Olympic Peninsula will close for maintenance and utility work. The closures include two lanes of I-90 between Eighth Avenue South and the floating bridge, US 2 between Money Creek Campground and Skykomish, and I-405 in both directions.

WSDOT states that the closures are for maintenance and utility work, with specific dates and times provided. The most significant closure is the full closure of northbound I-405 from Aug. 7-10, requiring a detour. Other closures will be overnight or during specific hours, with flaggers managing traffic flow.

The closures will affect drivers traveling through the area, with detours in place for some closures. WSDOT advises drivers to allow extra time for their trips and to check for updates before traveling.
